NEW YORK, Dec. 27, 2025, 6:12 p.m. ET — Market closed (weekend).
Coupang, Inc. (NYSE: CPNG) capped the holiday-shortened week with a sharp rebound after investors digested new details about a high-profile cybersecurity incident tied to the company’s Korea operations. CPNG last closed at $24.27, up $1.47 (+6.45%), after swinging between $23.89 and $25.34 on heavy volume of about 30.3 million shares. [1]
In extended trading after Friday’s close, CPNG was quoted around $24.42 (+0.62%). [2]
The move matters because U.S. markets are closed Saturday and Sunday, leaving investors to evaluate whether Friday’s rally was a one-day relief pop—or the start of a more durable reset in sentiment—before trading resumes Monday, Dec. 29.
Coupang stock price action: what moved CPNG this week
The immediate catalyst was a company update posted on Dec. 25 describing investigative findings “to date” around the cybersecurity incident at Coupang Corp., its Korean subsidiary. Coupang said it identified the perpetrator (a former employee), recovered devices used in the leak, and concluded the individual accessed 33 million accounts but retained limited user data from only about 3,000 accounts, then deleted the retained data. [3]
Markets responded to what many traders interpreted as a reduction in worst-case outcomes. Multiple outlets described the move as a relief rally after a volatile December driven by breach headlines and political scrutiny in South Korea. [4]
Friday’s broader tape also provided a backdrop: U.S. stocks reopened after the Christmas holiday with light volume and few major scheduled catalysts, which can amplify stock-specific swings like the one in CPNG. [5]
Cybersecurity update: what Coupang disclosed in the last 48 hours
In its Dec. 25 update, Coupang detailed several points that investors immediately focused on:
- The perpetrator allegedly never transferred data to others. [6]
- Coupang said the retained data included only 2,609 building entrance codes, and that no payment data, login data, or individual customs numbers were accessed. [7]
- Coupang said it commissioned Mandiant, Palo Alto Networks, and Ernst & Young to conduct forensic work. [8]
- The update also describes recovery of devices and evidence, including a MacBook Air that the perpetrator allegedly attempted to dispose of—detail that underscores the company’s effort to frame the incident as contained and investigable. [9]
Reuters separately reported that Coupang said a former employee committed the breach and deleted the downloaded data, but also noted that South Korea’s science ministry said the investigation was ongoing and it had not confirmed Coupang’s claim, criticizing the company for releasing information unilaterally before conclusions were reached. [10]
That unresolved gap—company assertions versus regulator confirmation—is one reason investors should expect headline risk to remain elevated even after Friday’s bounce.
Latest Coupang stock news: the key headlines from the past 24–48 hours
Here are the main developments shaping CPNG sentiment into the weekend:
- Coupang’s Dec. 25 statement: the company said an ex-employee retained data from ~3,000 accounts and deleted it; no payment/login/customs data was accessed; multiple global firms were engaged for forensic investigation. [11]
- Reuters (Dec. 25): reported Coupang’s deletion claim and emphasized that South Korea’s science ministry hadn’t confirmed those findings and criticized Coupang’s unilateral disclosure. [12]
- Investopedia (Dec. 26): highlighted the stock’s sharp rebound following the update, framing it as investor relief after the cyber incident pushed shares to their lowest level since earlier in the year. [13]
- Barron’s (Dec. 26): described the move as a surge tied to the “less bad than feared” conclusion and pointed to reputational and regulatory stakes after a turbulent month. [14]
- PRNewswire / Hagens Berman (Dec. 27) and GlobeNewswire / Rosen Law Firm (Dec. 27): both published notices around a securities class action tied to breach disclosure issues, including a stated lead plaintiff deadline of Feb. 17, 2026. (These are law-firm announcements, not court rulings.) [15]
SEC filing context: what the company has already warned investors about
A central document for investors is Coupang’s Form 8‑K filed in mid-December under Item 1.05 (Material Cybersecurity Incidents). In that filing, Coupang said it became aware of unauthorized access on Nov. 18, 2025, activated incident response, notified authorities, and warned customers whose data may have been accessed. [16]
Critically, the 8‑K states:
- A former employee may have obtained names, phone numbers, delivery addresses, and email addresses tied to up to 33 million customer accounts, plus certain order histories for a subset. [17]
- No banking info, payment card info, or login credentials were obtained, according to the company’s findings at the time. [18]
- Operations were not materially disrupted, but the company warned it could face financial penalties (not yet estimable) and “potentially material financial losses” from remediation and litigation, among other risks. [19]
- The filing also noted the resignation of the Korean subsidiary’s CEO and named Harold L. Rogers as interim CEO of the Korean subsidiary. [20]
This matters for the next session because any incremental disclosure—regulatory findings, new filings, settlement signals, or contradictory statements—could quickly reshape the market’s view of the downside tail.
Lawsuit watch: what “class action” headlines mean for CPNG holders right now
Over the last day, multiple law firms circulated public notices describing a securities class action tied to breach disclosures and alleged timing issues, including the referenced Feb. 17, 2026 lead plaintiff deadline. [21]
Earlier this week, Reuters reported that Coupang faced a U.S. securities class action following the breach, describing allegations that the company misled investors about cybersecurity and disclosure timing. [22]
For investors, the practical takeaway into Monday is less about the existence of “a press release” and more about what comes next in court: filings, motions, and any signals that litigation exposure is expanding (additional suits, broader class claims, or settlement talks). Those developments can take time—but the stock can react instantly to credible legal updates.
Analyst forecasts and targets: where Wall Street sees Coupang stock going
Even amid the breach overhang, aggregated Wall Street sentiment remains constructive—though it varies by source and updates at different cadences:
- MarketBeat lists an average 12‑month Coupang price target of $33.25 (with a range of $27 to $40), implying meaningful upside from the mid‑$20s. [23]
- Investing.com’s consensus page shows an average target around $34.98, with a high estimate of $40 and a low estimate around $28.6, also reflecting a generally bullish skew. [24]
On specific analyst actions, an Investing.com analyst-ratings report said Morgan Stanley analyst Seyon Park cut the firm’s price target to $31 from $35 while maintaining an Overweight rating, with the write-up noting expectations for minimal operational impact but acknowledging sentiment could take time to recover and modeling higher cybersecurity spending. [25]
Investors should interpret targets in context: many were set before full regulatory outcomes are known, and analysts may revise models again if penalties, remediation costs, or customer churn assumptions change.
Coupang fundamentals: what investors anchor on beyond the breach headlines
While the breach has dominated near-term tape action, Coupang’s bull case still rests on scale and profitability progress.
In its Q3 2025 earnings release, Coupang reported:
- Net revenues of $9.3 billion, up 18% year over year
- Gross profit of $2.7 billion, up 20%
- Operating income of $162 million
- Diluted EPS of $0.05 [26]
Those results help explain why analysts’ longer-term targets remain well above the current share price: the market is trying to price a fast-growing, logistics-heavy commerce platform while simultaneously discounting legal, regulatory, and reputational risks.
What investors should know before the next trading session
With markets closed until Monday, here’s what could realistically move Coupang stock (CPNG) at the open and during the next session:
- Regulator confirmation (or contradiction): Reuters noted that South Korea’s science ministry had not confirmed Coupang’s claim that the retained data was deleted. Any official findings, penalties, or public statements could shift perceived liability risk quickly. [27]
- New SEC filings or company updates: Coupang’s 8‑K already outlines potential exposure (penalties, litigation, remediation costs). Investors should watch for any updated risk estimates or additional disclosures. [28]
- Litigation escalation: class-action notices are circulating, but what matters is whether additional complaints appear, whether allegations broaden, and whether any new credible details emerge about timing or scope. [29]
- Year-end liquidity and volatility: late-December trading conditions can exaggerate swings—especially in a headline-driven name where short positioning and fast money can amplify gaps.
Bottom line for Coupang stock (CPNG) into Monday
Coupang stock ended the week higher as investors treated the Dec. 25 cybersecurity update as a “less severe than feared” development—yet the story is not fully resolved. The company’s own SEC disclosure acknowledges potential penalties and litigation exposure, and Reuters reporting highlights that regulators have not fully validated Coupang’s conclusions. [30]
Going into Monday’s session, the key question is whether the market continues to reward the narrowing of worst-case cyber fears—or re-prices risk as legal and regulatory processes advance.
